Application June 25, 1941, Serial No. 399,575

4 Claims.

The present invention pertains to a novel pad for use in forming waves in hair. The pad that is commonly used for this purpose consists of about two sheets of flannel stitched to a backing of aluminum foil, with a sheet or two of waxed paper, in book form. The aluminum foil freely sheds anywave lotions that may contact with it, and consequently the absorbent part of the pad must be dipped very carefully in the wave lotion to avoid contact with the foil. However, some carelessness may be expected, and the result is injury to customers from hot lotion.

The principal object of the present invention is to avoid this difficulty and also to provide a pad that does not require so much care in being dipped, so that the operation is faster as well as safer. Another object of the invention is to enable the use of less expensive materials, which moreover are not uniavorably affected under the action of the lotion and heat.

According to the invention, the novel pad consists of a body of crepe paper with a backing of kraft paper and a facing of blotting paper. The kraft paper is not only a substitute for aluminum foil but is slightly absorbent rather than shedding. The absorptive capacity of kraft paper is less than that of the body of the pad but not so high as to permit a surplus of lotion to be exuded therefrom in the heat treatment. Because of this property, it is not necessary to exercise great care to avoid wetting the backing. In fact, the entire pad may be and is entirely immersed in the lotion.

Other advantages of the invention will appear as the description proceeds in connection with the accompanying drawing in which:

Figure 1 is an end view of the general assembly for coiling, clamping and heating the hair;

Figure 2 is a cross section of the pad, and

Figure 3 is a perspective view of the pad.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 is illustrated the conventional apparatus for waving hair. The hair is passed through a base member I and wound on a curler 2. A pad 3 treated with hair waving lotion is wrapped on the curl, to be engaged by a heating clamp 4. Current is then supplied to the clamp through conductors 5.

As previously stated, the outer backing of the conventional pad consists of aluminum foil which does not absorb wave lotion. Injuries to customers have resulted from hot wave lotion being shed by the foil and burning the scalp.

In order to overcome this danger and to provide other advantages that will be described below, I employ a sheet 6 of thin kraft paper as the backing member. The body of the pad, laid upon the backing, consists of a suitable number of layers, according to thickness, of a highly absorbent paper such as crepe paper, indicated by the numeral 1. In order to secure the sheets together, they are pressed or annealed along parallel lines 8. The facing or the innermost sheet, whichis placed in contact with the hair, is preferably a sheet of blotting paper 9. Finally, the assembly is secured by a central line of stitching l0 extending lengthwise or transversely but preferably the latter. In this construction the body of the pad I is preferably glued to the backing 6. In a modified construction, the facing 9 may also be glued to the body 1 and the stitching eliminated.

The absorptive capacity of the kraft paper backing is suflicient to prevent any excess lotion from being shed by it. Consequently this pad requires less care than the foil-backed pad in being immersed. As a further result, the central stitching l0 becomes feasible. The dipping 01 a pad so stitched is easier and more complete than in the case of a pad with edge stitching, which is necessary where foil backing is used, inorder to avoid wetting the backing. In fact, as far as the kraft backing is concerned, the dipping operating may consist merely of throwing the pad into the lotion.

The facing 9 of blotting paper is considerably more absorbent than the kraft backing. The purpose of the blotting paper is primarily to prevent fibres of crepe paper from attaching themselves to the hair, and yet the blotting paper conveys the lotion to the hair at the proper rate. In other words, the blotting paper regulates the delivery of the lotion to the hair over a period of time, with the result that the action of the lotion on the hair under heat is more thorough than if unregulated.

Another property of the kraft backing is that paper, a backing of kraft paper secured thereto, and a facing sheet of blotting paper.

2. A hair wave pad comprising a body of crepe paper, a backing of kraft paper, and a facing sheet of blotting paper, the parts being secured together by a central seam of stitching.

3. A hair Wave pad comprising a body of crepe paper, a backing of kraft paper glued thereto, and a facing sheet of blotting paper, the parts being secured together by a central seam of stitching.

4. A hair Wave pad comprising a body of highly absorbent cellulosic material, a backing of slight- 1y absorbent material, a thin facing sheet of nonflaking absorbent material, and means securing said materials together.
